Course Objectives:

The objective of this course is to help you get an in-depth understanding of facemask media technologies, especially meltblown and emerging nanofiber technologies used to make the core components of protective facemasks against airborne contaminants, such as bacteria and coronaviruses. We will also discuss the test and certification standards for the facemasks, as well as market challenges, new developments, and trends for future development.

Session 1:

  • Introduction
    General facemasks and types of use
    Filtration principle of facemasks

  • Meltblown process design and web characteristics
    History and key players
    Fundamentals in meltblown process design
    Process control variables and web characteristics

  • Meltblown advantages for filtration and facemasks
    Unique meltblown structure
    Unique position in filtration

  • Electret meltblown polypropylene
    Electrostatic charging techniques
    Facemask applications
    Charge decay and durability

Session 2:

  • Nanotechnology and emerging nanofiber applications
    Nanotechnology and nanofibers
    Enhanced filtration performance and applications

  • Methods to produce nanofibers
    Electrospinning
    Meltblowing
    Forcespinning
    Electroblown
    Solution blowing, etc.

  • Nanofiber facemasks vs. meltblown electret PP facemasks
    Filtration performance
    Value proposition

  • Test and certification standards​

  • Unmet needs and future development trends

Instructor Biography

Christine Sun, Ph.D.

President @ Waterloo Filtration Institute

Dr. Sun is a globally renowned expert and leader in the filtration Industry. She served as the Chair of the American Filtration and Separations Society (AFS) from 2016-2017 and is the current Operation Chair of 13th World Filtration Congress to be held on April 20 – 24, 2020, San Diego, CA, USA. She received the AFS Fellow Award in 2019. With over 30 years of experience in both academia and industry, Dr. Sun has broad and in-depth knowledge of filtration and separation, as well as extensive and hands-on experience in product development. She finished her Ph.D. in 1995 in Chemical Engineering from Tsinghua University (Beijing) on “Meltblown Process Design, On-line Prediction and Optimal Control Using Neural Networks” and then worked for the University of Tennessee to continue her research on meltblown, nanofiber, and nonwovens until 2004. Dr. Sun worked for Freudenberg Filtration Technologies as R&D manager from 2004 to 2011, and then worked as Technology Director for Donaldson from 2011-2013. She developed the course “Nanofiber Technologies in Filtration” for American Filtration and Separation Society (AFS) in 2013 and the “Filter Media Training Course” for INDA in 2014. ‘The addition of INDA’s Nonwoven Filter Media Training Course was tremendously received’ said Dave Rousse, INDA’s president. Dr. Sun was known as “a brilliantly articulate and lively instructor who is skilled in guiding filter media professionals through the complexities of the air, liquid, and nanotechnology markets.” She developed several new courses recently for AFS, which were also highly-rated and well-received, including “Air Filtration Market, Technologies and Trends”, “Filter Media Technologies”, “Advanced Nonwovens in Filtration”, “Fuel/Oil/Lube/Hydraulic Filtration”, “Filtration in Transportation”, etc. Dr. Sun is now the president of Waterloo Filtration Institute (WFI). She works passionately with various organizations, societies, industrial and academic professionals worldwide to support the growth of the global filtration industry and advance the sciences and technologies of filtration and separation processes for a clean, healthy, and sustainable world. She has over 100 technical publications and multiple patents and has been actively involved in ASHRAE/ISO/SAE/NFPA filter test standard development for 15 years. Dr. Sun also serves as an editorial board member for Textile Research Journal and Journal of Industrial Textiles.
